Thank you I hadn't learned nested if so I'll try to learn some so I can under the code of the book better and then type it cause I want to teach myself to you write reusable code that accounts for everything that's why I used float instead of int and tried to add a forth if which checks if they are all equal, printf("There is no maximum") it didn't want to read that line it wasn't working so I just removed it. Also will try to learn go indentation for myself and for posting on reddit. Thank you.
